In this article I have explained how an input AC source could be increased to any desired levels using simple voltage multiplier circuits, built with capacitors and diodes. Thus the basic function of a voltage multiplier circuit is to multiply a given AC voltage source to any higher desired level, simply by adding the relevant […]

Transistor Multivibrator Circuits [Astable, Bistable, Monostable]
A transistor or BJT multivibrator is a two-stage switching circuit that is configured in a cross-coupled manner. This allows each of the active BJT stages to be regeneratively cross-coupled with the other BJT stage, so that one switches ON when the other switches OFF, and vice versa. This cross-coupling may be set up to switch either a […]
Wheatstone Bridge Circuits Explained with Calculations
A Wheatstone Bridge circuit is commonly used to measure resistance, inductance, capacitance, and impedance. These are made up of four parts or arms that are joined in series in a diamond like bridge configuration. These four arms carry the individual components such as resistor, inductor or capacitor connected across the fur junctions. An alternating current (AC) or […]
Simple Triac Triggering Circuits Explained
In this post I have explained the fundamental methods of triggering a triac, and also discuss the right way to connect the terminals of a triac. Triacs are solid-state bidirectional thyristors that can switch across both the AC half cycles on a 120-volt or 240-volt Ac power system. A triac could be activated (switched on and […]
Exploring Current Mirror Circuits with Practical Designs
In this post I have explained some important current mirror circuits, and how to design practical circuits using current mirror concepts. Current Mirror Definition A current mirror is a circuit that copies a current through one active device by regulating the current in another active device in the circuit, maintaining a constant output current independent […]
RGB Light Strip Controller Circuits
In this post we are going to see how we can construct an RGB LED light strip controller circuit for PC cabinets and also for general decoration purposes. In this post we will construct a couple of RGB light strip controller designs, one for a PC cabinets and one for general purpose which can be […]
